INHALING APPARATUS.

To all whom t may concern.-

Be it known that I, ALFRED JOHANNES \VASSMUTH, of Barmen, in the Kingdomof Prussia and German Empire, have invented a new and useful inhalingApparatus, (for which I have received Letters Patent in France, No.199,493, dated July 10, 1889; in Belgium, No. 86,952, dated July11,1889, and in England, No. 14,562, dated September 1G, 1889,) of whichthe following isa specification, reference being had therein to theaccompanying drawings.

This invention relates to a new or improved inhaling apparatus `in whichthe pharmaceutical solution used joins the air of the room .in such away that while the air is thoroughly impregnated no visible precipitatesappear.

The method of working the apparatusis as follows: The pharmaceuticalsolution is forced by means of a pump into the inhaling apparatus, whichis provided with a diffuser or spraying device, and it issues from theapparatus in the form of a fine cold vapor, which is discharged in theroom along with atmospheric air drawn in through apipe connected withthe diffusing device. The fresh air becomes intimately mixed with themedicated vapor. The principal novelty of the arrangement is that theair which joins the pharma ceutical solution is taken from theatmosphere instead of from the room in which the solution is beingdiffused. Openings are preferably made through the lower part of thewalls or the door of the room in which the inhaling apparatus is placed,so that when the fresh air, which is impregnated with pharmaceuticalsolution and is heavier than the air being used in the room, is admittedit will press the Vitiated air out through the openings in the floor orwalls. The inhaling apparatus is so constructed that'any liquid notquite vapor-ized will be conducted back again into the receptacle of thepharmaceutical solution.

The apparatuses used are reprcsei'lted on. the drawings annexed,whereon- Figure 1 shows the arrangement of the apparatus as used forinhaling. Figs. 2 and 3 show in part section and plan the interiorconstruction of the apparatus for diffusing the medicated vapor. Fig. Lshows in part section a modified construction of the same.

-The arrangement for inhaling, as represented at Fig. 1, is as follows:A pump a, moved by any mechanical power, forces the pharmaceuticalsolution under a pressure of from five to seven atmospheres out of thevessel I), which is filled through the funnel c, through the piped tothe diffusing or dissipatingapparatus e. The solution issuing throughthe spraying-nozzle CZ', Fig. 2, impinges against the apex of the cone cand is forced outward toward the space oropening g around the diffuser,from whence it issues in the form of a cold vapor. At the same time aconstant stream of fresh airis inducted through the pipeffrom the outeratmosphere. This inducted air combines and issues along with themedicated vapor. The quantity of fresh air admittedto the room in thismanner would be seven hundred to eight hundred cubic meters per hour.The viti ated air expired by the patient will be pressed downward andout through the holes 7.: in the walls. In this way the air will berenewed ten to fifteen times a day, according to the size of the room,and this renewal will take place without perceptible draft. As there issuch a constant and thorough renewal of air, any number of patientsmaybe allowed toinhale at the same time in the room without the airbeing seriously deteriorated. The patients inhale the impregnated airquite naturally. They may sit, lie, walk about, or even sleep while thepharmaceutical solution along with the air will enter their lungs. Anycondensed or superfluous solution collects in the bottom 7i of thedilfuser e and iiows through the pipe 1T back to the vessel l).

The inhaling` apparatus used in Fig. l is shown on an enlarged scale atFigs. 2 and 3, where, as before described, the pharmaceutical solutionis forced through the pipe d. to the diffusing apparatus, where itimpinges against the conical diffuser and is divided into minuteparticles, which combine and issue with the atmospheric air at g. Thepipe fconducts the air from outside the building into the case of thedistribnter or diffuser.

The apparatus represented at Figs. 2 and 3 IDO may be modified, as shownat Fig. 4. In this View Fig. 4 the dissipating` apparatus consists of acase a', made of any material, and Which is connected with the outsideair by 5 the pipe b. Between the case a and the pipe b there is a kneeor bend, the object of which is to collect any superiiuous or condensedliquid and allow it -to pass back through thepipe d to the forcing-pump.The spray-nozzle e', which is connectedlwith the force-pu mp by the pipef enters the vertical part c2 of the pipe above the bend. When using theapparatus the liquid is forced under considerable pressure along thepipe f in the direction of the arrow and through the spray-nozzle e'. Asitissues' from nozzle e', it strikes against the walls of the funnel g,and the conical cap h', driving at the same time the fresh air throughthe funnel g. The zo large particles of the solution drop down to thebottom of the Siphon-bend, so as to be carried away by the pipe d backto the forcepump, while the fine particles of the solution are forcedout of the apparatus at z" by the upward rush of ain After the apparatushas been started, the room is soon filled with the Vapor, and the air inthe room becomes like mist. The solution combines with the air sothoroughly that no perceptible precipitation 3o takes place. Vhen usedfor disinfecting purposes, the apparatus gives these advantages, viz.,it delivers the disinfectant in a Very finely-dried state anddistributes itint'o every corner of the room.

Of course no broad claim is made by me to the medication of air per se,as this has long been practiced.

What I claim, and desire to secure by Let- -ters Patent of the United`States, is-

vice, and a fresh-air-supply pipe jconnected with the diffuser, allsubstantially as shown and described.

2. In combination with air-pump aand reservoir b, the diffuser e,connected with the pump, a fresh-air-supply pipe f, also connected withthe diffuser, and a pipe t', extending from the diffuser back to thereservoir b,

substantially as and for the purpose exlplaiued.

In witness whereof I have hereunto set my hand in presence of twowitnesses1 ALFRED JOHANNES WASSMUllI.
